Key to species of Phlyctinus View in CoL
1. Ventrites 1 and 5 of male with erect golden setae forming two circular tufts ( Fig. 3B View Fig ); cavity of ventrite 5 extending over apical ⁴⁄5 of length, ventrites 2–4 with elongate tubercles at base of scales; external margin of eyes round, surface slightly conical in dorsal view ( Fig. 1B View Fig ). On Asteraceae View in CoL in coastal habitats .............................................................................. Phlyctinus grootbosensis View in CoL sp. nov.
– Ventrites 1 and 5 of male with setae more or less erect but not forming dense tufts ( Fig. 3A, C View Fig ), cavity of ventrite 5 extending only over apical ⅔ of length, integument of ventrites 2–4 smooth, lacking elongate tubercles at base of scales; external margin of eyes rounded, surface slightly conical or strongly conical in dorsal view ( Fig. 1A, E View Fig ) ................................................................................ 2
2. Cavity of ventrite 5 of male with erect setae along whole length of median area ( Fig. 3C View Fig ); body length> 7 mm; elytra of female with large tubercles and usually a contrasting transverse pale band on declivity ( Fig. 1C View Fig ); scales on prothorax dense, concealing integument, leaving only tubercles at base of setae and median carina visible; body of penis short, 0.5 × as long as apodemes; endophallus with a sclerotised plate forming a square angle below base of body of penis ( Fig. 2C View Fig ). Polyphagous, in inland valleys of Worcester region ................................................ Phlyctinus xerophilus View in CoL sp. nov.
– Cavity of ventrite 5 of male lacking erect setae in middle, or only present in basal half ( Fig. 3A, D View Fig ); body length <7 mm; elytra of female with no or only small tubercles and transverse, pale, contrasting or indistinct band on declivity ( Fig. 1A View Fig , D–F); scales on prothorax usually scattered, not concealing integument between tubercles and punctures; body of penis longer, more than 0.6× as long as apodemes; endophallus lacking sclerotised plate ( Fig. 2A View Fig , D–F) ........................................ 3
3. Scales on elytra always consisting of a mixture of wide and very narrow, hair-like ones ( Fig. 3E View Fig ); elytral declivity always with small but distinct tubercles on interstriae 3–5–7; eyes strongly protruding, surface conical in dorsal view ( Fig. 1A View Fig ); prothorax with 2 slight cuticular depressions on each side of median line; in female, transverse band of elytra generally extending over all interstriae. Polyphagous, widespread across the Western Cape province and introduced overseas ..................... .............................................................................................. Phlyctinus callosus ( Schoenherr, 1826) View in CoL
– Scales of elytra only elliptical in 95% of specimens ( Fig. 3F View Fig ); elytra with tubercles on declivity absent or very reduced on interstriae 3–5–7; eyes very protruding, with a conical surface, or not, in dorsal view ( Fig. 1 View Fig D–F); prothorax regularly convex, without cuticular depression; in female transverse band of elytra generally reduced to interstriae 1–3 ( Fig. 1D, F View Fig ) or lacking ( Fig. 1E View Fig ). Coastal habitats of the Kogelberg Nature Reserve ........................................................................... 4
4. Body integument covered with homogeneous greyish scales, a few paler spots scattered on elytra ( Fig. 1E View Fig ); eye margin round in dorsal view, or angled ( Fig. 1E View Fig ); body of penis widest near base, sides almost straight, converging apicad ( Fig. 2E View Fig ) ......................................... Phlyctinus littoralis View in CoL sp. nov.
– Body integument covered with brown, black or pearly green scales forming more or less contrasting patterns ( Fig. 1D, F View Fig ); eyes protruding, surface distinctly conical in dorsal view ( Fig. 1D, F View Fig ); body of penis with sides convex, widest near basal ½ or near middle of length ( Fig. 2D, F View Fig ) ....................... 5
5. Integument of prothorax with a smooth, shiny and very distinct carina in middle of length; vestiture of elytra forming a few ill-defined paler spots in addition to transverse band, this not always visible ( Fig. 1F View Fig ); erect scales on ventrites 1–4 shorter than claws; copulatory sclerite with setae at base of left arm ( Fig. 2F View Fig ) .................................................................................. Phlyctinus aloevorus View in CoL sp. nov.
– Integument of prothorax densely punctate, lacking longitudinal carina; vestiture of elytra with contrasting scattered pale spots in addition to transverse band ( Fig. 1D View Fig ); erect scales on ventrites 1–4 longer than claws; copulatory sclerite lacking setae at base of left arm ( Fig. 2D View Fig ) ...................... .......................................................................................................... Phlyctinus planithorax View in CoL sp. nov.
